Detecting version of installed GNAT

Detecting version of installed GNAT

[Marc A. Criley]

I'm looking for suggestions for programatically determining what version of 
GNAT is installed on a system.

I'd hoped there was something like "gnatmake -v" that would just display a 
version string, but gnatmake doesn't have that feature.  I could use "gcc 
-v" and then deduce from its version what version of GNAT was installed, 
but I'd prefer something more closely tied to GNAT itself.  And since some 
distributions of gnat use "gnatcc" instead of "gcc", I'd have to account 
for that as well.

It looks like I could compile a small file and then look at its .ali file, 
since that contains a compiler version string, but I'd still like to see 
something a little more direct.

Thanks for any suggestions.

Perhaps something like

gnatlink -v | grep GNATLINK

There is info in that for both FSF derived versions and GNAT GPL 
versions...Though its form is pretty different in each case.

Try

gnatls -v

Marc,

All gnat tools have a -v option. The version number is displayed just
after the tool name. Isn't that what you are looking for ?

-v seems to mean "verbose" rather than "version".

The simplest way seems to be "gnat | head -n 1".

The rules are something like:

If the second 'word' in the output line containing GNATLS is:

    GPL it's a GPL compiler

    Pro it's a Professional (supported) release

    I haven't seen what happens with GAP releases but I would expect
    GAP

and in all these cases the 3rd word is the release.

Otherwise, the second word is the release.

Here, I see

GNATLS GPL 2005 ...
GNATLS 4.0.0
GNATLS 3.15p ...
GNATLS Pro 3.16a1 ...
GNATLS Pro 5.02a1 ...

Doh!

gnatmake -v DOES show the version in the first output line.  It just 
then immediately follows it with all the Usage information.  And typing 
gnatmake alone shows all the Usage information.

As I simply saw all the Usage information scroll by when trying gnatmake 
-v, I didn't look it at closely enough, until after seeing Pascal's 
comment, to notice that the first non-blank line is in fact different. 
It's "GNATMAKE" followed by the version number, which is sufficent for 
my needs.

(Since I need to programatically invoke gnatmake, using that to as the 
source of the version is the most appropriate.)
